iTunes Seamless Play?

[Dark1]

The new seamless play feature is great but now I want to use it for  
some music I imported a long time ago.

It seems that some of the music I imported a long time ago doesn't  
organise its-self in the order as it appears on the CD where as more  
recent albums do.

I've got my iTunes organised by Artist in my library.  I don't want  
to reimport all my older albums for  2 reasons.  I can't be bothered  
doing it and also some of the CDs may have been scratched since I  
imported.

Thanks in advance
Ruben
